LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 554,038, dated February4, 1896.

Application filed November 20, 1 8 9 3.

To all whom it may concern.-

Be it known that I, JOSEPH C. SHULL, of Meriden, in the county of NewHaven and State of Connecticut, have invented a new Improvement inLamp-Burners; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a view in side elevation of one form which a lamp-burnerconstructed in accordance with my invention may assume, the gallerybeing shown in its depressed position; Fig. 2, a corresponding view withthe gallery shown in its elevated or lighting position; Fig. 3, adetached view of the gallery with a portion of it in vertical section;Fig. 4, a view of the gallery in transverse section on the line 00 0c ofFig. 3 and looking toward its upper portion; Fig. 5, a plan view of theburner with the gallery removed; Fig. 6, a View in vertical sectionthrough one side of the burner, showing the gallery in its verticalposition and one of the springs in engagement with the upper edge of theouter wick-tube.

My invention relates to an improvement in that class of lamp-burners inwhich the gallery is adapted to be raised and lowered for lighting thelamp without removing the chimney.

\Vith these ends in view my invention consists in certain details ofconstruction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claim.

In carrying out my invention as herein shown I provide the gallery A ofthe burner with a depending sleeve B, adapted in its dimensions to fitover the outer wick-tube C of the burner and to slide up and down freelythereupon and corresponding in size to the central opening of thegallery, into which its upper end is directly connected, as shown inFig. 6. The said sleeve B is constructed with openings B, which arelocated slightly below its upper end and which permit a match or otherlighted taper to be applied to the wick over the upper edge of the outerwick-tube C when the gallery is raised, the said openings Serial No.491,454. (No model.)

being arranged so that when the gallery is depressed the said wick-tubecloses them and cuts off any draft through them to the flame. Forsustaining the gallery in its elevated po- 5 5 sition I provide the saidsleeve with springs D, arranged with their free ends downward. Thesesprings are formed integral with the sleeve in the vertical portions Bthereof lying between the openings B. As shown, the sleeve has four ofsuch openings, and hence four vertical portions; but only two of thelatter are constructed with springs. If desired, however, all of thesaid vertical portions may be provided with springs. The lower end ofeach spring is constructed with a beveled retaining-shoulder cl, andeach spring is bent or set so that it will exert a constant efiort tospring inward Within the line of the sleeve and within the line of theouter wick-tube C. Then, therefore, the gallery is raised so that thelower ends of the springs are elevated above the upper edge of thewick-tube, the springs will at once spring inward over the upper edge ofthe same, as shown in Fig. 4 of the drawings, and thus support thegallery in its elevated position. Owing, however, to the beveled form oftheir retaining-shoulders, they are easily dislodged from the upper edgeof the wick-tube and caused to spring outward and ride upon the outerface thereof when the gallery is forced downward into its depressed ornormal posi tion.

By preference, also, I provide against the accidental removal of thegallery from the wick-tube. As herein shown, I accomplish that end byforming in the depending sleeve B of the gallery, in one of the verticalport-ions B thereof, athree-armed flute, the respective portions ofwhich are arranged at a right angle to each other and co-operate with aprojection C, formed in the outer wick-tube C. The said flute comprisestwo vertical clearance portions E E, and a horizontal stop portion Einterposed between them. When the gallery is applied to the outerwick-tube, the portion E of the flute is aligned with the projection C,whereby the sleeve is permitted to slip down over the tube until theprojection engages with the upper wall of the outer end of the stopportion E of the flute. The gallery is then rotated until the inner endof the said stop portion of the flute, and hence the vertical portion Ethereof, has been brought into alignment with the said projection, thuspermitting the gallery to be depressed into its normal position. In theordinary elevation and depression of the gallery the portion E of theflute clears the proj ection C and permits the gallery to be raised andlowered, but it is prevented from being removed from the tube by theengagement of the projection with the lower wall of the inner end of thestop portion of the flute; but the gallery may be rotated somewhatduring its elevation or depression. It is not, however, likely that inany ordinary use of the burner the gallery, and hence its dependingsleeve, will be rotated enough so but what the lower wall of the stopportion of the flute will somewhere engage with the projection andprevent the removal of the gallery. It is also a simple matter to rotatethe gallery to bring the short vertical portion E of the flute into linewith the projection, after which the gallery may readily be removed. Ihave shown only one flute and projection, and that is sufficient forpractical purposes; but two may be employed, if preferred. Nor do Ilimit myself to the use of a flute and projection for coupling thesleeve of the gallery with the outer wick-tube of the burner, for someother means might be used in their place.

The outer wick-tube is combined with a collar F and perforated skirt G,both of ordinary construction and requiring no detail description. Thegallery is also furnished with the usual spring-fingers A for claspingthe chimney.

I would therefore have it understood that I do not limit myself to theexact construc- .tion herein shown and described, but hold myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of my invention. ever, that it is old to construct alam p-burner with a gallery adapted to be vertically moved forconvenient access to the wick, and to connect friction-sprin gs with thesaid gallery and arrange them to ride upon the wicktube so as to supportthe gallery in its elevated position. I do not therefore claim such aconstruction broadly.

I-Iavin g fully described my invention, what I claim as new and desireto secure by Letters Patent, is-

In a lamp-burner, the combination with the gallery and the outerwick-tube thereof, of a depending sleeve corresponding in size to thecentral opening of the gallery, extended at its upper end directlythereinto and connected therewith, adapted to fit over the outerwicktube, and to slide freely up and down thereupon, constructed belowits upper end with lightingopenings which are closed by the outerwick-tube when the gallery is depressed, and also constructed with oneor more integral vertical springs arranged with their free endsdownward, struck out from those portions of the sleeve lying between thesaid lighting-openings, set to spring inward to engage with the outerface of the outer wicktube upon which they ride up and down, and havingtheir lower ends bent to spring inward over the upper edge of thesaidouter wiclv tube forsupporting the galleryin its elevated position, andto be sprung outward by the said tube when the gallery is depressed,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
